If the file length is known, the full width of the bar is the known length. Otherwise the initial width represents Kbytes and is doubled whenever the current width is exceeded. In non-interactive use this uses a text version. On Windows, if mode is not supplied missing and url ends in one of. An invisible integer code, 0 for success and non-zero for failure.
For the "wget" and "curl" methods this is the status code returned by the external program. The "internal" method can return 1 , but will in most cases throw an error.
What happens to the destination file s in the case of error depends on the method and R version. Currently the "internal" , "wininet" and "libcurl" methods will remove the file if there the URL is unavailable except when mode specifies appending when the file should be unchanged. This is usually done using the CA root certificates installed by the OS although we have seen instances in which these got removed rather than updated.
Note that the root certificates used by R may or may not be the same as used in a browser, and indeed different browsers may use different certificate bundles there is typically a build option to choose either their own or the system ones.
The "libcurl" methods uses passive mode, and that is almost universally used by browsers. Setting the method should be left to the end user. Neither of the wget nor curl commands is widely available: you can check if one is available via Sys. If you use download. The supported method s do change: method libcurl was introduced in R 3. Files of more than 2GB are supported on bit builds of R ; they may be truncated on some bit builds.
